SHUTTLE-BOX FOR ROTARY-BOX LOOMS.

No. 882,361. Specification of Letters Patent. Patented March 17, 1908. Application filed October 23, 1905. Serial No. 284,029.

forming part of the box-supporting frame 22 which forms a cup-bearing in which the inner end of the shuttle-box rotates, the bearing 16 being cut away as shown at 17 opposite the shuttle-race. 60

The bottom 4 of each compartment is beveled as shown in Figs. 2 and 3 to suit the bevel of the shuttle-race, when the latter is not at a right angle with the reed. Suitable shuttle-retaining ledges 19 are provided for 65 each compartment, being formed upon the bracket pieces 9, which are secured to the plates 2.

An additional bar 25 such 'as is used with vertical boxes is employed connecting the 70 outer bracket with the going-part and acting as a stay for guiding the picker, and mounted in the present invention in such a position relatively to the picker spindle 26 that the picker 27 bears against it during its forward 75 and inward stroke so that the picker maintains a vertical position throughout the stroke. The picker fork 28 receives the picker after the stroke and maintains it in a vertical position while at rest. 80

In Fig. 4 the modified arrangement shows plates 2 in which the width of the sides of the square axial shaft 1 may be the full width of the compartment, the shaft being turned down between the securing points of the 85 plates to reduce its increased weight. In this construction the extension 2 of the plate 2 beyond the shaft 1 may be arranged to To all whom it may concern:

Be it known that we, ALBERT EDWARD ALKER, ARTHUR WALKER, and GEORGE ALKER, all subjects of the King of Great Britain, residing at N orwood Green, near Halifax, England, have invented a certain new and useful Improvement in Shuttle- Boxes for Rotary-Box Looms, of which the following is a specification.

The invention relates to the shuttle-boxes of rotary-box looms, and has reference to a novel and improved construction and mounting of the same which enables the shuttlebox, by the simplicity and strength of its construction, to be applied to and work upon the loom with greater mechanical precision and efficiency than is ossible with the usual construction of shuttfe-box.

n the accompanying drawings: Figure 1, is a front elevation of a rotary shuttle box constructed in accordance with this invention. Fig. 2, is an end elevation of same looked at from the direction of the arrow on Fig. 1. Fig. 3, is a section on line a, b of Fig.

1. Fig. 4, is an end view illustrating a slightly modified construction of box.

he axis of the shuttle-box is a square shaft 1 which forms the foundation for the bottom of each compartment in a shuttlebox of four com artments. To each side of the shaft a meta plate 2 is secured by screws or the like 3 the series of plates being placed upon the shaft 1 successively in the same direct-ion as shown.

Each plate 2 is common to two com artments forming on the outer side 4 of the plate the bottom of a compartment and on the inner side 5the front wall of a compartment.

At the required distance from .the front wall 5 of each compartment the swell 6 is mounted by being lvoted at its fulcrum end u on a stud 7 or t e like firmly fixed on the pate 2 its free end 8 (Fig. 1) resting in a racket-piece 9 or other suitable support secured to the plate 2. The swell is ressed inwardly by a flat spring 10 securec to the late.by a fixed pin 11 and a screw 12 and bent as shown at 13, at right angles to meet 0 the swell 6, or by other convenient means.

ment. In the latter case the front 5 of the compartment may be fixed upon the plate by a bracket 9 at each end, which brackets also carry the swell 6 of an adjoining compartment.

The shuttle-box is mounted at its inner end in a cup-bearing 15, 16 carried by the bar 18 of the box-supporting frame 22 as already stated, and at its outer end the shaft 1 is turned down and carried in a divided bearing 21 as shown in Fig. 1, the upper half 21 of the bearing being detachable and screwed upon the lower half 21 which is fixed upon the box-supporting frame 22 or forms part of shaft at each end of the divided bearing pre- 1 Vhat we claim is 1. In shuttle boxes for rotary-box looms comprising several compartments, the combination of an axial shaft forming the foundation for each compartment, bearings for said shaft, a series of plates secured to said shaft so that one side of each plate forms the bottom of a compartment, and part of the other side of same plate forms the front wall of an adjoining compartment, a swell to each compartment and means for retaining the shuttle in each compartment, substantially as described.

2. In shuttle boxes for rotary-box looms comprising several compartments, the combination of an axial'shaft forming the foundation for the shuttle box, bearings for said shaft, a series of plates secured to said shaft so that one side ofa plate forms the bottom of a compartment and part of the other side of the same plate forms the front wall of an adjoining compartment, a swell to each compartment, and supports having shuttle-rataining ledges for each compartment, substantially as described.

3. In shuttle boxes for rotary-box looms comprising several compartments, the combination of an axial shaft forming the foundation for each compartment, bearings for said shaft, a series of-plates .secured to said shaft so that each plate is common to two compartments, a swell for each compartment, and bracket pieces provided with shuttle retaining ledges secured to said plates for carrying said shuttle-retaining ledges, substantially as described.

4. In shuttle boxes for rotarybox looms comprising several compartments, the combination of an axial shaft, an end bearing for said shaft, a series of plates secured to sai shaft so that each plate is common to two compartments, bracket pieces provided with shuttle retaining ledges and having arcs formed thereon, and means for admitting a shuttle into a compartment, comprisinga circular plate having an opening therein and a flange forming a cup said arc-shaped bracket pieces are capable of revolving,

swell for each compartment, bracket pieces secured to each plate within which the free ends of said swells rest, a spring secured to each plate for controlling the motion of the swells, said bracket pieces having shuttle-retaining ledges for each compartment, substantially as described.

6. In shuttle boxes for rotary-box looms, the combination of an axial shaft, bearings for said shaft, a series of plates secured to said shaft so that each plate is common to' two compartments, a swell for each c0rnpart ment, bracket pieces carried by said plates against which the free ends of the swells rest, and having shuttle retaining ledges, substantially as described.

7. In shuttle boxes for rotary-box looms, comprising several compartments, the combination of a square axial shaft, bearings for said shaft, a series of plates secured to said shaft and forming compartments, the extensions of said plates forming compartments, bracket pieces secured to said plates and forming the entrances of said compartments, and a swell for each compartment carried by said brackets, substantially as described.

8. In shuttle boxes for rotary-box looms comprising several compartments, the combination of driving means, l shaft forming the foundation for each compartment, a series of plates secured to said shaft so that each plate is common to two compart ments, end bearings for said shaft, a rotary box supporting frame carrying said bearings, a picker and a bar connecting the outer part of the box frame with the driving means and acting as a stay for said frame and as a guide for said picker, substantially as described.

In witness whereof we have hereunto set our hands in the presence of two subscribing witnesses.
